We have a Lutron lighting system which was installed in 2008, I am not sure which system it is. Last night when we went to turn on the lights, they would not go on (except for the bedroom/bath control), unless we went into the switch in the garage and pressed "Home" in which case certain lights went on. When we press any of the switches the house (again, except for the bedroom/bath), they just blink and the lights will not goon.
